CHARLES c. TOMKINSON, or

SHEET- Application filed November 18,

State of New Jersey, have invented certain new and useful Improvements in Sheet-Pil ing, of which the following is a specification.

My invention relates to piles, and particularly to interlocking piles, such as are used in making sheet-piling for coffer-dam work and the like.

Its object is to provide a pile which shall shall be very rigid and easily driven, and shall be economical, because of its being made of standard sections and-of which the selvage when the pile is pulled up shall be practically complete.

Further objects of the invention will appear in the specification and will be pointed out in the claims.

In the drawings, Figure 1 is a top plan view of a portion of a Coffer-dam or the like, showing the interlocked piles in their driven position. Figs. 2 and 3 are similar views showing a modified construction of piles. Fig. 4 is a similar view of a single pile of a further modifiedconstruction. Fig. 5 is a partial sidevelevation, and Fig. 6 a perspective view, of the lower portion of a pile, showing a shoe therefor.

Referring to Fig. 1 of the drawings, each of the regular piles 1 consists of two troughbeams 2 and 3, the webs 21 and 31 of which are parallel to each other and the flanges 22 and 32 of which extendv in the same direction. Between the webs 2] and 31 of the beams 2 and 3 is placed a wood timber or filler 4, the thickness of which is somewhat greater than the height of the flanges 32 on the beam 3 and the width of of the web of the beam 2, so as to permit the flanges 32 of the larger beam 3 to be driven between the edges oft-he timber 4 and the flanges 22 of the beam 2, as clearly shown in the drawings. The channel-beams 2 and 3 and the timber filler 4 are securely fastened in vertical alinement.

The manner of driving shown in the drawings, in which it will be seen that the'piles are successively driven with the webs 31 of the wider beams 3 back these piles is clearly Specification of Letters Patent.

to back and with the flanges 32 of these beams interlocked between the web 31. of the beam of the next pile, the flange 22 of the narrower beam, and the side of the wood filler 4. The swelling of the wood filler 4 presses the edges of the timber firmly against the outer side of the flanges 32 and secures a perfectly water-tight sheet. At the lower right corner of Fig. 1 is shown a pile 6', consisting of a channel-bean1 61, the web of which is bent to a right angle at about its middle line, a timber flller 41 being secured by bolts 5 in this angle and so as to swell and bear against the flanges 32 of the adjacent piles on each side of the corner.

At the lower left corner of the drawings is shown a simpler form of corner-pile 7, which consists of a channel-beam the web of which is bent to an approximately quadrant al curve, so that its flanges between the web 31, the flange 22, and the timber filler 4 of the adjacent piles.

Where it is desired to stiffen the piling or dam by a cross-partition, a pile 8 is used, which consists of a channel-bar 3. and a second channel-bar 9 of a width intermediate between those of the channel-bars 2 and 3, already described. As before, the webs 91 and 31 of the channel-bars areparallel and spaced apart by a timber filler 4, the parts being secured by a bolt 5. v

As shown in the drawings, the lateral flanges 92 and 32 of the channel-beams are parallel with each other and are secured by rivets 51 to a third channel-beam 3, the flanges 32 of which are, as before, interlocked with the adjacent piles on each side.

In Fig. 2 of the drawings I have shown a modified form of piling in which a channelbar 3 is secured to a metal member (shown as a plate 10) by bolts 52, a wooden timber or tiller 4 being secured between them, as before. It will be seen that the flanges 32 of the channel-bar 3 interlock with each other and with the ends of the plate 10, as before, and that, as before, the lateral swelling of the timber 4 acts to make the joints water-tight. In this drawing I have shown one ofthe piles as provided with Z-shaped beam 11, having flanges 112, one of whichis bolted to the channel-bar 3 of the pile and the other of which interlocks with the flange on the adjacent pile, as shown.

The form'of pile shown in 3 is similar 72 are, as before, locked IOC V to those. shownjn Fig. 2, except that; thechannelsbar 3-is replaced by abeam 12, the

flanges 122 of which are at an obtuse angle:

with its web 121. The fillerAl inthis case is of a prismatic shape to fit closely when swollen against the flanges 122 of the a dja -i cent beams. I have shown a corner of this dam as formed of two of the beams 12, the:

flanges32 of the. channel-bar -3; secured,

thereto, while the otherflanges133=merely act to strengthen and, stiffen the plate.

It wilLJoe noted, that inallg these forms ofconstruction one of the two parallel members is provided with lateral flanges projecting toward the other member,: and that this? second member has a substantially flat web, the widthof WhlGlI'lS equal to or greater than: the width of the first member, including the flanges. thereon, thereby'providi'ng for ;-the interlocking of the. iles.

To secure the easy driving of the -piles of whatever form made; I may provide them-- with the shoe shownin Figs. 5 and 6,- which consists of a plate 14,;haviing two parallel faces 141-and 1428 1161 an -inter media te portion 143 bent at an acute angle Wi-th'thepor tion 141, the angle lt i inclosi'ng the lower 7 shown may Lbe made vmy devicewithont' end of the web 31-"ofjth'e channel-bar3-and beth portions 141 and- 142-being bolted to i the webs 31 and'21 of the barsfifand 2, re spectiyely. As shown,th e filler-4 may-ad- .vantageously-be beveled at its, lower end 42 to fill and stiffen the interlocking portion of the shoe.

It isgobvious that changes -thertha-n those departing from the spiritjof the invention lt isebviou that the advantages of theinventi'on are, the simplicity of -,construction of the ,piles, owing tothe fact that theyaremade of standard sections which can bepnrchased in? open 7 market, the, ease withrwhioh they may bedrivenin their interlocl'iedposition,

the wa ter-tight wall which gis produce'd, and z the almost perfect selvage;which- --res1il-tswhen the piles are withdrawn byreason-of thefact thatthetaking out cf the bolts 5 leave the-jmetal beamsor sectionsancr even the ,ti-mber filler' impractically the same condig somew at they were before using?
